The mass of the Earth is significantly greater than the mass of Mars. The Earth has a mass of 5.972 × 1024 kg, whereas Mars has a mass of 6.39 × 1023 kg. This means that the Earth is about 9.4 times more massive than Mars. Despite their difference in mass, their proportions remain relatively similar, as the Earth’s equatorial radius is roughly 3.38 times larger than Mars’s.
